Summary
Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in ....Fluorescence Detector for the Australian National Beamline Facility. X-ray absorption spectroscopy (XAS) is an extremely important synchrotron radiation tool for determining the local structure around an X-ray absorbing atom. This has many applications in the study of materials, minerals, metal complexes, and metalloproteins and can often be used to obtain information that is not available by other techniques, because structural information can be obtained in the solid or solution state and in mixtures. The current proposal is aimed at introducing new technology into the Australian National Beamline Facility that will greatly improve the quality and quantity of experiments that can be performed and extend studies into dilute solutions and protein samples.Read moreRead less
Cooperativity in Spin Crossover Systems: Memory, Magnetism and Microporosity. Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism. Here we aim to synthesise and study a wide variety of new spin-crossover systems where cooperativitiy between centres, induced by careful supramolecular design, will lead to molecul ....Cooperativity in Spin Crossover Systems: Memory, Magnetism and Microporosity. Spin-crossover centres are a well known form of inorganic electronic switch for which variation of temperature, pressure and irradiation leads to a change in d-electron configuration and therefore changes to structure, colour and magnetism. Here we aim to synthesise and study a wide variety of new spin-crossover systems where cooperativitiy between centres, induced by careful supramolecular design, will lead to molecules and materials having memory retention, magnetic ordering and/or microporosity. The significance of these aims covers several fundamental questions in the science of electronic systems. We also identify a number of potential nanochemical switching applications for the unique systems proposed.Read moreRead less

Magnetic materials are important through their use in recording tapes and other electronic devices. Traditional magnetic materials are metals, alloys or metal oxides made by high temperature methods. Our aims are to synthesize new chemical and molecule based solid materials which possess the properties of traditional magnets but which are made by careful chemical design at ambient temperatures. We will make materials which have three-dimensional network structures or large clusters of ions such as manganese bridged by organic molecules. Their magnetic properties will be studied in detail.

Australia faces significant environmental and technological challenges including development of clean, sustainable energy sources and technologies that do not adversely affect the terrestrial atmosphere. This project seeks to facilitate a cleaner, greener future through investigations of fundamental chemical interactions responsible for hydrogen storage in solid media, and atmospheric processes responsible for the production and destruction of ozone. In both cases, the key interactions between ions and neutral molecules will be elucidated through high-resolution laser studies. Ensuing experimental data will play a crucial role in controlling and predicting ion-neutral interactions in technological and environmental contexts.Read moreRead less
Towards a Microscopic Understanding of Anion Solvation. Atomic and molecular anions are ubiquitous components of oceans, rivers, lakes, and the atmosphere, and serve as key participants in natural and industrial chemical processes. In most situations ions are surrounded by a structured sheath of neutral solvent molecules which profoundly affects their physical and chemical properties. Currently, interactions between anions and solvent molecules are poorly understood. In this project we will use ....Towards a Microscopic Understanding of Anion Solvation. Atomic and molecular anions are ubiquitous components of oceans, rivers, lakes, and the atmosphere, and serve as key participants in natural and industrial chemical processes. In most situations ions are surrounded by a structured sheath of neutral solvent molecules which profoundly affects their physical and chemical properties. Currently, interactions between anions and solvent molecules are poorly understood. In this project we will use lasers to probe clusters consisting of just a few molecules attached to an anion, generating information that will enhance our ability to predict and control chemical processes involved in drug design, salination, atmospheric chemistry, and chemical waste remediation.Read moreRead less

Increasingly, the design of new pharmaceuticals uses computer modeling to account for the shapes of molecules and how they interact with their surroundings. The strongest forces between molecular components are those that involve charged chemical species known as ions. In this project, we will develop advanced laser-based techniques to study in unprecedented detail how molecules respond to the presence of nearby charge, or to acquiring charge themselves. Understanding the nature of these attractions, and the structural changes that they induce eventually results in more accurate computer models. This has relevance to fields that include the architecture of proteins, recognition of signaling molecules in the brain, and drug development.Read moreRead less

We will employ novel spectroscopic strategies to probe the structures of mass-selected anion complexes and clusters in the gas-phase with the purpose of exploring non-covalent forces responsible for anion solvation.

We will employ novel spectroscopic strategies to probe the structures of mass-selected anion complexes and clusters in the gas-phase with the purpose of exploring non-covalent forces responsible for anion solvation. The work is motivated by a recognition that anions serve as key participants in a host of natural and industrial chemical processes, and that their physical and chemical properties depend critically upon interactions with solvent molecules. The experimental results should serve as a critical test for computational approaches to describing anion-neutral interactions, and provide new insights into the behaviour of electrolytes, acid-base chemistry, and fundamental bimolecular reactions.Read moreRead less
